# XL Systems Improve Facility Power Factor

**POWER FACTOR**

Power Factor is the ratio of Real Power (Watts) to Apparent Power (VA). When current and voltage are in phase, power factor is 1. As circuit inductive loads (motors) retard the current waveform it falls out of phase and lags the voltage waveform. If current lags voltage by 10%, power factor is 90% or 0.90. As magnetic fields build up, it takes more time for current to reach its full value in inductive loads.

**TIS TEST RESULTS (500 HP MOTOR)**

Test results show an average INCREASE in Power Factor of 0.132 or 18.7%. XL Systems improve power factor through the magnetic chokes which increase energy efficiency in inductive loads such as motors.
